LU-13258 libcfs: fixes for cfs_arch_init()

The introduction of cfs_arch_init() brought two problems.

1/ wait_bit_init() wasn't known due to a missing include file.
2/ cfs_arch_init() was not marked __init, but it called
   a function (wait_bit_init) that was.

This patch fixes both of these.

Fixes: 3453c95f513c ("LU-13258 libcfs: make apply_workqueue_attrs() available for Lustre")
